Presenting HarperCollins Publishers All-American Dogs. President Biden’s German shepherds are the latest in a long line of presidential dogs. Dating back to George Washington, dogs have been companions to 31 of the past 46 of America’s presidents. Organized by historical eras, this book journeys through the White House’s four-legged residents, their impact on their pet-parent-in-chiefs, and ultimately, American history. From the tragic assassination of President Lincoln’s dog after his own death, to President Hoover’s Belgian shepherd, King Tut, who helped him win the election after appearing in a campaign photo, these furry members of the first family often left a lasting impression on the administrations that kept them. As the historian-in-residence at the Presidential Pet Museum, Hager brings original research and rare photographs from the National Archives. From post-Revolutionary dogs to Civil War era dogs, and even Cold War dogs, readers will discover the differences and similarities in how our nation has viewed man’s best friend.
